You're quite welcome.
I'm still in awe of the place myself, even after hiking down to the bottom. I guess I'm even more awed when I begin to realize what a huge time frame is there, and what a huge time frame ISN'T there. Considering that the vast majority of sediments in the modern record are from two or three-day storm events over hundreds or thousands of years, what you're seeing is a massive set of disconformities let alone the 'Great Unconformity' under the Cambrian beds. Add to that that the top of the Grand Canyon is Permian in age (greater than 225 million years old) and you're seeing just a MINUTE FRACTION of the sedimentary rock record.
Look at it this way. You go down to Florida today in the Florida Keys, and you start taking cores of the sediments on land, and all you see are storm deposits left by hurricanes. Three inches here from Andrew, three to six inches there from Betsy, and eventually you get down to the Pleistocene after seeing a myriad of storm deposits. Bedrock may be twenty inches down or it might be a number of feet, and it's all that's left after the last 100,000 years of repeated cycles of erosion and sedimentation. If you measure sediment accumulation (and believe me, the University of Miami, the University of Florida, the USGS, and every geologic organization and entity have looked at it at one time or another) then you see that offshore sediment accumulation rates are measured in millmeters every few hundred years. By comparison, the Grand Canyon is what, a mile or more deep? That's over 1.6 million mm.
You do the math, and geologic time makes you feel insignificant compared to its vast tapestry. It makes your day when you realize that you can view the color, the beauty of it all and it was over a billion years in the making. Friggin' AWESOME.
That's why the God seen by evolutionary theorists is so much more awe-inspiring than that seen by creationists. He had the time to do it right, not a few thousand years to cut a 'big ditch'.
